Standard diameters for bolt holes are 1/16” larger than the bolt diameter. 2 The anchor bolts are intended for anchoring structural supports to concrete foundations. Only weak relationships exist between plate thickness and load capacity. (Alternatively, the angle may be fillet-welded to the column. Atmus is a distributor of bearings, power transmission, motion control and pneumatics. for the ultimate bearing capacity of a continuous foundation with centric inclined load and presented formulations of ultimate bearing capacity of such footings. In addition, bolts generally have a greater load bearing capacity than screws but lack a tapered shaft. Note: RISAConnection considers all three equations in this section (J3-6a through J3-6c) for the Bolt Bearing checks. Promoting our products. Toggle bolts are sized in two ways by the diameter of the machine screw and by the length of the machine screw.
